Answer:
She can send 200 messages....
Step-by-step explanation:
We have given:
Josephine is on a cell phone plan where she pays $20 a month plus $.10 per text message she does not want to spend more than $40 on her cell phone bill
The equation we get is:
20+0.10x<=40
Now solve the inequality:
20+0.10x<=40
Combine the like terms:
0.10x<= 40-20
0.10x <= 20
Divide both sides by 0.10
0.10x/0.10 <= 20/0.10
x <= 200
She can send 200 messages....
